— an advanced type of TFT matrix, created on the basis of the so-called. low temperature polycrystalline silicon. Allows you to easily create screens with a very high pixel density (more than 500 PPI - see above), achieving high resolutions even with a small diagonal. In addition, some of the control electronics can be built directly into the matrix, reducing the overall thickness of the display. The main disadvantage of LTPS is its relatively high cost, but nowadays such screens can be found even in budget smartphones.
